echo "The /mnt/hdd/temp directory is for short time data and will get cleaned up on very start. Dont work with data here thats bigger then 25GB - because on BTRFS hdd layout this is a own partition with limited space. Also on BTRFS hdd layout the temp partition is an FAT format - so it can be easily mounted on Windows and OSx laptops by just connecting it to such laptops. Use this for easy export data. To import data make sure to work with the data before bootstrap is deleting the directory on startup." > ./README.txt mv ./README.txt /mnt/hdd/temp/README.txt 2>/dev/null
